transfer switch model numbering system. The sample model
number shown is for a Model ZCB programmed-transition transfer switch with M340+
microprocessor electrical controls rated at 600 volts, 60 hertz, 3 phase, 3 poles, and 4 wires in a
NEMA type 1 enclosure with a current rating of 1000 amperes. Not all possible combinations
are available.
